Abstract

A tool is proposed to assist detachment of an apparatus which has a housing adhering flatly on a pane, particularly of a sensor on the front windscreen of a vehicle, in which the apparatus housing has a surface with an exposed edge spaced from the pane. The tool has the form of a lug which has at least one engagement member on one longitudinal end, which engagement member can be engaged on the exposed edge of the apparatus and is provided with an opening or recess for a lever tool at a longitudinal distance from the engagement member. The tool is applied to the apparatus by engaging the engagement member behind the exposed edge on the apparatus housing. Then the lever tool, e.g. a simple bar or a screwdriver, is pushed through the opening or recess and is applied to bear on the top of the apparatus housing. The free end of the lever is then slowly raised, thereby lifting the housing off the pane.

Description

TOOL Field of the Invention The present invention relates to a tool for helping to remove an apparatus having a housing, adhered in a flat manner on a glass, particularly a front windshield sensor of a vehicle. BACKGROUND OF THE INVENTION Appliances such as rain sensors, often combined as rain / light sensors, are pressed onto the interior surface of a vehicle's front windshield with the interposition of a transparent elastic coupling layer.

This coupling layer, consisting for example of a silicone material, adheres to both the glass and the coupling surface of the sensor after a certain period of time.

When changing a damaged front windscreen it is also difficult and requires intense work, if the coupling layer is torn off during disassembly of the front windshield. Brief Description of the Invention The invention provides a simple tool with which the front windshield sensor can be removed in a simple manner. The tool according to the invention is designed to help remove an apparatus having a housing that adheres flatly on a glass, particularly a sensor on the front windshield of a vehicle, wherein the housing of the vehicle The apparatus has a surface with an exposed end away from the glass. The tool has the shape of an ear having at least one longitudinal end coupling member, which coupling member can be engaged at the exposed end of the apparatus and is provided with an opening or recess for a lever tool to a longitudinal distance of the coupling member. The tool is applied to the apparatus by coupling the coupling member behind the exposed end of the housing of the apparatus. The lever tool, in this case a simple bar or screwdriver, is pushed through the opening or recess and applied to resist in the upper part of the housing of the apparatus. Then the free end of the lever is slowly raised. The lever movement is transferred as traction on the ear, where the adjacent end of the apparatus is lifted from the glass. By raising the lever end further, the apparatus is then tilted more and more towards its end, which is still in the glass, and in doing so is removed from the glass. A particularly advantageous embodiment is suitable for a rain / light sensor, which is mounted by means of a holder frame attached to the glass. Here, the support frame surrounds the sensor housing, forming a reduced space around the housing. The tool is now constructed so that the coupling member forms an elastic pull tab at the end of the ear. The ear is inserted with the pull tab perpendicular to the glass towards the surrounding space, until the pull tab engages under the exposed end in the sensor housing with a pull sound that can be clearly seen. The tool is then held securely in its mating position and is also guided in its movement through space. BRIEF DESCRIPTION OF THE FIGURES Other features and advantages will be apparent from the following description from the attached figures, wherein: Figure 1 shows a perspective view of the tool's diagram; Figure 2 shows a top view of the tool; Figure 3 shows a sectional view along the line B-B in Figure 2; Figure 4 shows a sectional view along line A-A in Figure 2; and Figure 5 shows diagram views to illustrate the use of the tool. DETAILED DESCRIPTION OF THE INVENTION The tool 10 shown in the figures is a portion of perforated metal sheet in the form of an elongated flat ear. At the longitudinal end of the body of the ear, the tool has three pull tabs 12, punched therefrom and angled at an angle of about 15 °, and also has a small round hole 14 approximately in the center between two ends longitudinal At the other longitudinal end, the body of the ear has a larger round hole 16, which forms a grip opening. A reinforcement rim 18 is stamped along the outer periphery of the ear body in a region spaced at a distance from the pull tabs. The tool is particularly suited to assist in disassembling a rain / rain / light sensor from the front windscreen of a vehicle, as will now be described in more detail with reference to figures 5 to 8. In figures 5 to 8, the sensor it is illustrated in simplified form with a sensor housing 20 in the form of a parallelepiped. With the interposition of a coupling layer 22 of a transparent silicone material, the sensor housing is pressed against the inner surface of the front windscreen 24 of a vehicle. In addition, a support frame 26 is fastened, particularly glued, to the interior surface of the front windshield 24. The holder frame 26 surrounds the sensor housing 20 and is separated from it by a small distance, so that a small gap 28 is formed around the housing 20. The tool 10 is now inserted in this gap 28 as shown in the figure 7, in this case in a direction perpendicular to the front windshield 24 and pointing to the sensor housing 20 with the pull tabs. While the pull tabs 12 penetrate the narrow gap 28, they bend a little backward in a direction of the body plane of the ear. He sensor housing has an exposed end 20a on its pointing surface and which is slightly separated from the front windshield. If the tool 10 is now pushed further into the gap 28, then the pull tabs 12 finally engage back from the exposed end 20a of the sensor housing 20. In so doing, the pull tabs are elastically retracted into their angled position. At the same time, the end of the tool that is inserted in the gap 28 presses against the surface of the front windshield. Both procedures involve a clearly noticeable sound. The operator can now be sure that the tool is engaged in the gap 28 and the current disassembly procedure can be started. To do this, in the next step a simple lever tool 30 is pushed by the hole 14 of the tool 10. This can be a bar or a screwdriver, which is easily accessible. The end of the lever tool 30, which is pushed through an opening 14, is applied at the end of the sensor housing as far as possible from the tool 10 to resist in its upper part, as shown in Figure 8. Then the lever tool 30 is taken and lifted slowly. The articulation movement of the lever tool 30 is converted into a traction which is transferred by the tool 10 onto the sensor housing 20 and allows the sensor housing to be lifted from the front windshield 24. With the upward movement of the lifting tool 30, the end of the sensor housing 20 adjacent to the tool 20 is released and it begins to rotate about its edge that moves away as much as possible in the tool 10. In this way the apparatus disassemble the front windshield 24 in a delicate manner and without any damage to the sensor housing 20 or the coupling layer 22.
